Need help in choosing new PALs

I am currently wearing Rodenstock Life C lenses. I have a new
prescription in which my right eye has gone from -6.25 to -6.00 in about
a year, and my optometrist thinks this will help with reading and other
close work. (This eye was -6.75 about 2.5 years ago; the left eye has
stayed the same throughout. I am 59 years old.)

The whole new prescription is:

O.D.:
Spherical: -6.00; Cylindrical: +0.25; Axis: 170
O.S.:
Spherical: -7.75; Cylindrical: +0.75; Axis: 071
Prism in both is: 1(with small triangle superscript)
Base in both is: BI
Add for Near is: =2.50

What differences would there be between the Rodenstocks I am now
wearing, and the Shamir Genesis? I am particularly concerned with width
of the reading area and how far down in the lens it is, but am
interested in other differences you may note. Would one of these lenses
be better for my prescription than the other? Is there another lens that
would be better than either of these for me?

Thanks for your help. Making this choice is very confusing for me.

I doubt that there are more than a few opticians in the country who would do
this.

 

I'm thinking I'll probably go with Varilux Panamic in a 1.6 index. That
would be better for me than the 1.67, wouldn't it?
